Abstract
An embodiment relates to a method for determining a slope of a slide in a slide scanning device, which includes: (a) obtaining, by a scanning control unit of a slide scanning device, z-stack images for at least a partial area of a sample of a slide; (b) extracting, by the scanning control unit, a z-axis location of a slice image in which a focus evaluation value has a top value of a predetermined ranking along a plurality of lines of any one of a plurality of rows or a plurality of columns of the z-stack images as a slope calculation z-axis location; and (c) calculating, by the scanning control unit, a slope by using a distance according to a location of a horizontal plane of the plurality of lines and the slope calculation z-axis location, and estimating the calculated slope as the slope of the slide.
